Located in the Okinawa archipelago, Yonaha-wan is the biggest tidal flat on Miyako Island and is one of the largest in the Ryukyu Islands biogeographic region. The site supports mangrove forests and extensive seaweed beds mainly composed of Thaalassia hemprichii, Cymodocea rotundata and Syringodium isoetifolium. A significant number of waterbird species stop at the site to forage or breed, including the critically endangered Spoon-billed Sandpiper Eurynorhynchus pygmeus and the endangered Japanese Crane Grus japonensis and Oriental stork Ciconia boyciana. A number of reptiles are also recorded in this marine sanctuary, such as the critically endangered Hawksbill turtle Eretmochelys imbricata as well as endangered endemic species such as the Miyako Grass Lizard Takydromus toyamai. The area is important for fisheries, tourism and environmental education and is currently affected by the inflow of excess nutrients and sediments from agricultural and domestic sources.
